5/5 Optic LED Optic 6 Grow Light

Optic LED with the CREE COBs and the Sleek Design I received a Optic 6 recently and when i opened it up the first thing in noticed was the secondary reflectors, and the big fat reflectors on the cobs. After turning the LED on and setting it up I began to like it more and more. IT puts out beautiful white light when the cobs are on, and in VEG im only running the 5w leds which is consuming only like half the power. I love how theres a button to turn just the cobs on and off independently and it has the worlds easiest timer to use, its not the KIND LED that takes a rocket scientist to configure. All in All i recommend this light to any grower looking for HIGH PAR output for a 4x4 coverage area.

Great costumer service Have not recived the light yet, just placed the order a few hours ago. However the costumer service was great. I had a buch of questions and concerns, all of which were solved by guy named David who explained to me with detail the difference between the two light fixtures that I liked. We were on the phone for half an hour just talking, he never rushed me or tried to sell me anything in particular, he just answered every question I had. The information he gave me was not only very useful but was also detailed and explained very clearly. Wish I had employes with the same initiative as this guy, I hope the rest of the process is as good as the ordering was, will write a review on the light as soon as it arrives

She's Sturdy This light is very effective and has many features that make it stand out. The coverage area and penetration are very good with the Optic 6 and the plants appear healthy and grow rapidly underneath it. I started using this light while my Viparspectra 600 was being repaired under warranty. During this time I discovered the many benefits of having a high powered LED. The best benefit was the high PAR output and low heat discharge. I am operating the original Optic 6 with only a 54" inch ceiling height. The Optic 6 is a very durable light and I trust it to do the job safely. Thanks to Ledgrowshop and OpticLedgrowLights
